Tow jaw pin problem

[Erie Fred]

I found a 10' x 3/16" Keetona folder/press brake in Buffalo for about $4k last year.....

Ahh bingo. I suspect you are right. Barely any slop.
Is it time to dig out my Nato hitch perhaps?

Can still be done with a pin/ball combo fizzy, got a couple that have about an inch more clearance behind the pin than the standard set up you can have.I am at Eds in a couple of weeks, can bring it with me.

I have a pintle hitch from an army truck, it's on a swivel.

Cheers thanks for that.
Ring is about 55mm internal diameter.

Of course it’s powered! Manumatic or handraulic are the usual descriptors for one like that.

What is a standard jaw designed for? 40mm?
Mine is 50mm.

Wow they travel a long way.

...and they don't look like they would float all too well either.....

My neighbor has one very similar that when the leaf is down you can't tell it's powered.
Has a ring segment gear and gear motor underneath. The segment pushes up in the middle of the leaf.

Bob - thanks very much for the offer!
I was lucky and spotted a bargain on Ebay. £10 so very happy.
Probably be fun to change - KNOTT

My temp antitheft measure until I make a proper one to fit. High quality Squire padlock.

Not had much to do with ring hitches apart from using my home-made solid drawbar in my rally recovery days so been doing a bit of reading up and apparently the ring should be big enough that it contacts the back of the jaws before hitting the pin to apply the trailer brakes, every day a school day.

That's right, pull on the pin, brake on the jaw.

Fizzy , I was thinking ..( my left foot hurts ) make a slip in & out the tow hitch pulley so it nestles against the ring then use a bit of hydraulic ram as the pin , there must be some hydraulic cylinder refurbishers locally . Get them to put the top flange & handle on it and taper & drill the bottom end as required then specialist coded weld it for you . They might also have some already made pins for excavators etc. that are not cheap Chinese mild steel stuff.

The over run brake friction sleeve might need adjusting as well as it is a new unused chassis trailer that has only had it's first run out journey . Adjust it so it take a bit of effort to slide the tow eye in and out of the trailer mounting tube .
